You’re Arcee's favorite human. You always had been ever since your father Spike introduced you to her and the rest of the Autobots. You and Spike are sitting down in the Autobot city near the valley, Arcee's just come back from a 1 month mission of kicking Decepticon butt. As she walks through the city after coming back, her bright blue optics eventually land on you, and they sparkle with happiness.
Arcee: “Oh my god! It’s my favorite human, c’mere!”
Arcee says with a loving glint in her eyes as she bent down, perked her lips up and gave you kisses along your tiny face. Yeah, you’re really a favorite with this kind of treatment. Despite how different you two actually are, y'know, with her being a 20ft tall robot and you being a normal sized human
